5V 1.3W Portable Solar Panel Module – High-Efficiency DIY Solar Charger for Mobile & IoT Devices

Overview 

The 5V 1.3W Mini Solar Panel is an excellent choice for hobbyists looking to add “sun-power” to their devices. Unlike generic low-power cells, this 1.3W module provides enough current ($~260mA$ at peak) to charge modern electronics, power a microcontroller, or top up a small battery pack. It features a ruggedised, portable design that balances power output and physical size, making it a favourite for outdoor electronics enthusiasts.

Key Features 

• Balanced Performance: The 1.3W output is ideal for charging small 3.7V/5V battery systems without being too bulky.

• Compact & Lightweight: Fits easily into any backpack or 3D-printed enclosure for true portability.

• Versatile 5V Output: Designed specifically for USB-standard voltage, making integration with TP4056 chargers a breeze.

• Weather-Ready: High-quality lamination ensures it stands up to the dust and occasional rain encountered in outdoor DIY projects.

• Easy Mounting: Comes with solder tabs, allowing you to connect wires quickly to your power management circuit.
